I think at one point you are going to overload yourself. Not from learning no, you may have the mind frame to suck all of that in. But you will be overloaded by jobs you are taking, because in your mind "YOU CAN DO IT" because you learned it.
This is what I would advise you. Find what is your strongest artistic point. Let's say it's web design. Web design includes what:
- UI/UX methodology
- A bit of knowledge in HTML/CSS
- Picture quality
You can see that just in Web design, there are 4 big departments you need to learn, to be good at it :Graphic Design, UI/UX methodology, Coding, and photography (not much though).
Considering that each department might lead to something. Like Mobile design for example, By Learning UI/UX you definitely Learn about Apps Design, App UI, etc. So you mean to tell me that after all that you are going to turn around, and go work on a Motion graphic project, in which you might be stuck at one point, because you need a random 3D element, to achieve a certain effect? Because what will happen is, if you are passionate you close after effects, go open C4D to learn how to do that 3D effect for your After Affect Motion design. Then in C4D you will stumble on a problem of lighting. You see how by the time you get to C4D you already forgot about your Web design thing?
My point is there is not really a bad way. But you learn by bulk. Here is how I did if that can help.
I started with Photomanipulation on Photoshop (Actually Photofiltre and GIMP) for about a year and a half, Then I got bored by that because I felt like I already much, I wanted to learn how to create Adverts, that is what introduced into creating logos. I learned how to do that on Photoshop not illustrator. In the meantime I was interested in how to make my logo move around and be animated. And then, and then and then. It's been 8 years I'm into digital Arts, and throughout those years, I touched Photo Manipulation, 3D graphics, Motion Graphics, Video production. Today I'm a web developer who is learning only photography and photo retouching. Now you see I have a background in all of that because I found out that my end goal is to be an Art director. But I didn't learn that all at once, passion led me to learn new things to better myself first.
So this is what I can tell you. Don't learn stuff on top on stuff or all at once just because you want to be able to say "I know how to do that". Do things because there is a calling, and learning it will help improve yourself. Focus on one department, learn the in and out. Take one month and focus only on Logos. Learn how to brand it, how to present your logo a client, then take two months to animate them until you are satisfied with your animation. If you are not satisfied in 2 months, give yourself another month, etc.. etc.. till you feel like you are ready to move on to new departments to better yourself. That's what I did.
