Welcome to the forum @anithikos!
I’m sorry but this is a working thread, not a general advice thread, and the rules of this post (first post) ask you to pick a working, perform it and post the results/images of the performance here. We do ask people to wait 90 days of activity before performing work for others. Stick around and join in our discussions and in 3 months we’d love it if you came back here to post your performed workings. 
After that please do make your next post your Introduction here, which we need per the forum rules and see our posting guidelines in the FAQ.
Points to cover:
-
Do you have any practical experience in magick?
-
If so, what exactly do you practice and how long have you practiced?
-
Do you follow any specific system or tradition?
-
What are your areas of interest?
Here is a getting started with magick guide. You’ll want to get your spiritual hygiene sorted out, and start work on developing your astral senses, then when you can know you have a decent chance at avoiding impostors and parasites then try the evocation guides we have on here.
