Some good and bad points:-
Good Points:
You get to make the decisions
You can plan your time to suit you
You answer to no-one but yourself
You can earn the kind of money you want to. (the more you put in the more you will earn)
Bad Points
You may have to wait to get paid
You dont holiday or sickness pay as employed
You have to do all the jobs, answer phone, type letters, clean the van etc
You have to build up your customers
You have to control your own accounts (unless you pay an accountant)
You have to pay the tax man
You will need business insurances etc
Obviously its no walk in the park and sometimes you will think and wished that you just had a job and got paid regular every week. Most people I know who work for theirselves say its the best move they ever made and wouldn't go back to working for anyone else again.
