I would suggest you find a supplier close to you (trust me, you want one as close as possible) and get a kit. Make a few candles from that kit, and see how you like it. Decide if you want soy, paraffin or a blend. Burn the candles in your home and see if you like how they perform, then friends will ask, and build from there. But trust everyone when they tell you, it's not an inexpensive hobby. If you find you like making candles, etc. then look in your area for scents that sell, how many other candle makers are in your immediate area and be different. Upscale v. rustic, bakery scents v. natural scents, etc. As in any business you need start up costs, licensing, insurance, product, materials, marketing. But this is a good way to start. Oh...and learn all of the terminology on the board, it will help a lot.
