nninezee Let me just say: I started out Blender with huge plans, but with a growing family, and a demanding job I already have that pays all my bills. For me I had to eat the reality that either I quit my job and tell my wife to handle everything until I become an absolute pro like Wes' friend did, or I just do this to de-stress as a hobby activity. That was 3 years ago. I'm still a noob albeit a much better noob than I used to be. I feel like I am slowly building my experience, but I also get to keep my good paying job and my wife and kids feel appreciated most days, haha.
To each their own. I hope you take the necessary steps for what you want to accomplish.
Ill also add my perspective...I think that starting from scratch, three months is a very short time. Maybe it would be better to split this goal into smaller manageable parts. Lets say, your first goal is to get through some basic blender course and learn basic features and UI. Then do a project where you will put those skills to a test. And then just work on that until you are finished and happy with the result and then move to a next goal. This way you will hopefully keep yourself from burning out, because each smaller goal will feel like an achievment and motivate you to keep going. As opposed to getting stuff done but still feeling like you are miles away from this one huge goal you gave yourself. And it is a really huge goal, there is just so many things to learn if youre starting from scratch.
However if you work on it you can learn pretty fast. You gotta practice every day and for many hours. Which brings me to my second point....practicing like this is a pretty huge commitment and it is really hard to do if youre doing it for some big goal in the future, instead of because it is fun for you. And if youre a complete beginner you cant really know if you will enjoy it as much as you might think. My point is...dont work like a slave only to learn a bit faster. Work on it and practice a lot but do it at your own pace and in a way that is fun for you. At least thats what works best for me, I figured this out pretty recently. Before, I wanted to complete every project as fast as possible and that made the whole thing kind of stressful for me. But now, when I do personal project I take it easy dont rush anywhere. And I am able to spend way more time on it than before and in the end get stuff done faster.
But I would seriously advice you to give yourself more time. Three months is really short. When I started with 3D about a year and a half ago, the first three months I spent every moment i had learning and doing projects. Basically I was just working a couple of night shifts a week, I skipped 90% of school (my school had nothing to do with 3D) and all the time I had I spent learning. I was sleeping way less than I should have and my eating habits were pretty bad too. And even though I made huge progress, when I now look at the work I did before, there is so many mistakes that I would not put it in my portfolio without redoing the whole thing :D
Anyway after 3 month I went back to my country for christmas, got a taste of what it is like to live a civilized person and then I took it more easy. I didnt practice very consistently and sometimes didnt do anything for weeks. But I guess I needed those breaks at the time, but during those breaks I forgot a lot of stuff which I needed to relearn again. I think it is possible, that if I took it more easy during those first 3 months, I would not have had this burn-out, and overall made bigger progress than I did. It took me maybe another half a year before I got out of this burned out phase.
But it all worked out in the end, I found an internship at a game studio, and then started freelancing. I cant really say that I make a "living":D I survive from paycheck to paycheck but I feel like im on the right track. And now that I figured what kind of mind set works best for me, Im having more fun with 3D than ever.
I didnt expect to write this much....but I hope there something in here that might help you. Anyway, I encourage you to learn as much as you can and I hope it all works out for you. But dont do it just because of the job you one day might have, do it because its fun, because thats whats going to keep you going.
