doesn't the fact that your self taught in so many professions and yet not fully successful in any of them, and now your looking round for something else to add on to make up your wages, doesn't that tell you something?
decide what you want to do, wether it be gardening, mechanics, painting, window cleaning, or even carpet cleaning, put all your efforts into it, including the best training possible, (its free if you look carefully for it) not just for the job but for marketting and general running of your business, even web design and stuff comes in handy. once youve done that you shouldn,t need to look for other ways to make money.
there are loads of successful gardeners out there who aren't looking at anything else to add on cos there to busy. bet they studied not just how to cut grass but have a knowledge of plants shrubs and everything else that contributes to being a success. you can't learn on the job what time of year a rhodidandrum needs planting
just the same, you can't learn on the job why a B/W will shrink, and yes, you can wet clean them.
training gives you confidence which the customer notices.
training gives you a better result.
training speeds you up.
training is paramount to every successful busines in my eyes.
training my friend, is a must.
