1) Launch in nice open spaces where if anything goes wrong uve got plenty of room downwind
2) launch 90 degrees into the wind the third time i went out my dad hot launched me still have a grass burn scar on my foot 3 years later
3) Get someone who knows wat ur doing to launch ur kite tell them ur a beginer and they will give u good advise. I would not recommend learning self launch/land yet as u need to get used to how the kite reacts
3) watch videos on self rescue and go practice it easier if u have shallow water
4) right kite size for wind for a beginer you waste a bit of wind so u want to be powered
These are just tips to keep u safe as far as kiting goes ur skills get better the more u perservere just dont be afraid to swoop kite hatd when water starting and know how to body drag
Goodluck
