Anyone a vegan? Any tips?

I always said, that someday in the future I will become vegetarian. And I think I feel ready now. I feel like I don't want to eat meat no more, like I got no taste for it no more. Also I feel so low energy lately, and I hope that would make me more lighter on my feet.
I don't really want eggs either. Milk is tasty, but I siwtched to soya milk a while ago. Only thing is that Imma miss cheese.
