Hi, qualifications,exams and certs aside....i have worked for myself,in one form or another since i was 10 years old and THIS is what you will need,not in order of importance; Patience,stamina,confidence,ability to assess a persons character in first 5 mins,investing in your job before yourself (equipment and knowledge before holidays and gadgets...) and another valuable asset is having like-minded pals in other trades you can drop on when stuck...ie: finding severed SWA at 4 pm,phone call at 4.30 pm, Mini-digger and pipe bedding there at 8 am the next morning. Also try to have a really great missus,and,when needed,growing a massive set of balls. I hope this is of assistance,as it's from the heart :willy_nilly:
