So anyone who is taking this serious which is less than you might think but still a very large group of people, if you are not pushing it, spending as much time as you can then you are cheating yourself, time will pass and you'll only end up half as good as you should be if you're lucky, so study study study
At times i find it difficult RSI, migraines, general fatigue and the old classic procrastinating, most artists will face these problems but dedication will pull you through most of the time and if you don't make it to the other side then hopefully it was because you weren't as commited as you thought you were not because of more serious ailments
