I think most, if not all artists feel like this every now and then. Some dont even like their own work :s You just need to be inspired. Find something that'll spark your imagination. TRY RELAXING. AND NOT THINKING ABOUT IT helps me :}
I trained for Martial Arts , i got stronger . Then a guy,weaker than me and stupid beat me up . I was/am verry sad and i think i don't have the right to train for Martial Arts now ,beacause i am a shame to Martial Arts . But i will train harder and longer and crush all my fears . Conclusion : You need motivation to do that ,so do i ...and allot Hope this helps
I only do a new sig when I have an idea. There isn't any right or wrong in design, so there's no need to force yourself into accepting something like "I gotta design something now." So take a break, forget about it, do other stuff and come back when an idea actually hits you.
"writers block" stems from overworking and overthinking. And most importantly, it stems from your own self-confidence. Stop working for a while, until you feel the urge that you absolutely have to to start creating again. Things will flow naturally.
I agree, get laid
