My first ever tip is probably the most important tip. Please do never forget this tip!
HAVE FUN!!!
You should not care what other people ever think of you, while doing something you like (without hurting other people). In photography there are a lot of people whom forget that making photos is supposed to be fun. If somebody ever makes you feel like making pictures is not fun, do not listen to them.
If you are not technical forget technical stuff. I will explain you the technical stuff in an easy as possible way. Settings are easy, experience can be gained.
Do never think you are better than somebody else, especially if you never saw their pictures. If somebody thinks he is not as good as you, maybe he or she wants some tips?
