Well done
bd01uk - good on ya!
Yes, I agree best to start simple - but also important to have a plan and set some goals to get your flying off to a good start.
First up, I'd go out local on my own before taking up any friends / family, and just to enjoy
After this, maybe one or two local flights with friends / family - but make it easy on yourself by doing this in EXTERMELY GOOD conditions, and on a route you are familiar with as sometimes recently qualified people can find it an almost overwhelming sense of responsibility to have "innocent victims" aboard - keep your stress load light, and take time and care to brief your passengers properly. I always make sure they know how to get out (if I break my arms, I want someone else to be able to open the hatch!) and I also remind non-flyers that I don't want their feet near the rudders when I take-off/land, nor near the yoke unless I say "you have control". There was another thread on taking pax the first time a while back with lots of other "gotchas" to bear in mind.
Next, I'd find a flying buddy at a simialr stage as yourself to team up with, i.e. someone you get on with and who has also recently attained PPL, say in the last 6 months. You should then set yourselves some reasonably challenging trips to do together so you can both build experience, share cost, and boost each others confidence. I recently wrote more on this on a thread called
Advice on X-countries in the UK which you might like to read.
Good luck! Remember, try to fill the cup of experience before you empty the cup of luck!!!
