I dont know if a thread like this was posted before, but the idea is as follows: tell us the mistakes you commited so that other people dont commit them!, what a genius idea!, i think this is one of the most powerfull ways of learning, from others, learning from their mistakes. Here are mine: - Wasting too much time doing nothing, learning nothing, waiting for nothing, i spent like 2 years like this and i could have spent them making games, or learning to draw, but i was too stupid at that time, i could be so much better at everything now, so dont do as i did, get your goals clear, now, and work on them, now. - Not excersizing: spending all days sitting on a desk without any kind of sport or excersize can make your energy levels drop to dramatic levels, in my case i got so little energy on the day that i only could work or study half of the day, it was imposible for me to get up early since i got so little energy, and i even needed to take naps!, but since i got to do some runnings and stuff like that for maybe 10 minutes a day, i dont need to take naps and i can get very early in the morning if i wanted. So, making excersize gives you more energy to do more stuff in the day, you absolutelly need it if you are indie. - Hating math: i hated math when i was at school, in the end i didnt learn anything of it, i thought it was a useless thing, and of course boring,all that changed when i realized the truth when i started to make games, how important maths are!, i wish i paid attention to my math classes, i wish i didnt thought it was a useless thing!. Lesson learned: never listen to your ignorance, learn from everything you can, you may need it badly some day.
