Hi there Mariaam, congrats! Interior design is a wonderful profession.

And to answer your question... I would look for a good design school in your area and try to get into a program. If you can't afford the time or the money to do that then I would suggest taking as many online design classes as you can. In addition, I would find a good local designer to mentor you, hopefully you can learn on the job if you can intern with a good design shop. Hope this helps. Lyn Mabry
