I think every single person has the ability to be creative. they just need to try. I suck at drawing so I much prefer abstract painting so nothing has to look realistic.
Of course you can do it Ruchie!!! Just try whatever inspires you the most. I find I produce nicer things if I'm inspired.
I also think that art is a great stress reliever and emotional release (just like music). You can be in your own little dream world. It can give you more self-confidence when you amaze yourself with what you've produced!
