@Men in Black - This is your refereeing journey and you will take out as much as you are willing to put in. I know its an old cliche but it is so true.
My refereeing journey follows a similar path to yours, i was playing up until my mid 30's then ran a couple of teams and as this all came to an end I wanted to stay involved in football and refereeing seemed to be a logical step.
When I first started I had no real aspirations for my refereeing journey but, similarly to you, I felt I could do a better job than some of the officials currently doing it, especially as they have been around since I started OA football. I tried to referee the game the way I wanted it refereeing as a player, my first game I don't even remember doing a boot check as I didn't want to be "That" referee, i do equipment checks religiously now so much so I have them all line up on the nearest white line and walk up to check the boots and down to check the jewelry.
All teams want is a referee to apply the LoTG fairly and consistently, we are there after all to facilitate the game of football!
Over time I joined the promotion scheme as it was a great way to get feedback on what you do well and what you need to improve. I also did a couple of AR appointments early on and it was great to be part of a team and to see how other referees in action. Much like playing its about getting into good habits and its those referees who don't have good habits who are still at L7 doing the worst games. (NOTE: Not all referees at L7 have bad habits, I know some really good L7 referees who have never wanted to be promoted)
My first season i was probably too lenient (no one wants a booking on a sunday morning) despite all the abuse/dissent, I even felt like jacking it in thinking it wasn't right for me, year 2 i was probably too strict and only now after 3 years did I feel ready to progress. I gained promotion from 7-6, officiated in a prestigious local cup final and been awarded a county cup final line. I have started taking AR appointments on supply leagues which is another experience altogether (1-1.5 hour meets before each game, suits, post game refreshments etc) but I have learnt so much doing those appointments with L4 referees that I feel my refereeing has improved.
No one is Howard Webb after completing the course and we all find our own "way" of refereeing but it does happen over time and once you get to that point you should start to enjoy it more.
