First off, it takes time. Everything does! But magic is all around us, and a witch while seemingly thrilling, sure isn't all it's cracked up to be.
For one, you can't become a ''witch'' overnight. You also weren't born into a witch(though you could have been raised from family of witches). A witch in my opinion, is someone who works and respects the area around them. Many will say a witch casts spells, but while this is true, its not necessary!
Second becoming a witch and starting to practice witchcraft is serious. You could loose your house, job, friends, ect. So be careful who you tell, or don't tell at all.
If you become a witch, it'll take time. First learn the basics. Grounding, meditation, ect. These will help you out, and it will certaintly help in terms of knowing what to do. I suggest reading a few boks, and articles or forum posts on SoM here. AwakeTooLong's is good.
