Hi Pooja. Things to keep in mind before choosing a career in arts:
Develop Your Skills. Before you can begin a successful career in art, you must first develop solid artistic skills.
Make a Studio Space.
Find Your Artistic Voice and what drives you.
Make Yourself Known by being unique.

Choosing a career in arts is generally considered uncertain but by going through a structured approach you can make it less uncertain and do amazing in it. Hope this helps.
