my top tip - learn to start both ways. I see a lot of footage of people taking off switch for some reason. Definitely surfers and supers that have never kited or windsurfed. The efficiency of a switch stance is about 3/4 that of a proper stance and you cannot go upwind as well either. Mostly tho practice, practice, practice. You will get a feel for how much power in the wing will get you up - which will get less and less as you get better. Add in waves and swell and its another ball game. Windblown waves are the worst as they take away your apparent wind. I like to use them on the way out - provided you have enough wind to be stable and resist a hit. As the wave throws the front of your board up - you have gained some potential energy that can be turned into forward speed - the foil wing will slow the decent thru the water - so throw yourself forward and start pumping the back of the wave will also be downhill giving you something to pump into . Finally - save your energy- dont just pump and flail wait for a gust AND water that you can release from - pumping in short chop an d light winds can be a waste of time if the chop hits you and kills momentum.
