Hey mate
I have only just started this as well and I have not even been able to get up on the board yet. However, practice is the key they say

On the topic of trying to teach yourself,
I am a full time uni student, due to which I aint the richest person at the moment

. I know it is probably not ideal due to the timeframe, but I had a 2 hr lesson 6 weeks ago, and another few hr one last week. Just trying to point out that if you don't have heaps of cash it is not a lost cause kind a thing. Just space the lessons out a bit, and you will be more than ready before the nice summer season starts again.
So, like everyone says i would not recommend not having lessons. I personally experienced when I was practising with my instructor's kite, that the wind can change in an instant, especially during winter, and it can get quite scary out there when you are on your own...
Speaking of the weather, besides all the reasons others have listed, it is probably a good idea to know from an instructor in what conditions you should and should not fly your kite, and of course how to do it

As i said i am only new at this too and don't know much about it yet, but hey, happy kiting! hope you will enjoy it as much as I do. can't wait until i can learn some more
