The Future Is In Your Hands!: One of the reasons that you might want to start on your own business venture is because you hate having a boss that tells you what to do all the time. Well guess what, the biggest perk of having your own business is that you call the shots and can do things your way. What would you rather? Work for someone who moans every time your late or when you need to take a day off. Someone that's breathing down your neck every five minutes or would you prefer to turn up for work in pyjamas and take a holiday whenever you felt like it?
This may surprise you but actually working for your self can be a lot less stressful than working for a boss that always knows better than you.

Earn Lot's Of Money: Let's face it working for someone else all of your life will limit yourself to becoming wealthy. A basic wage will not lead to the road to riches, even if you move up the company I believe the most you will receive is a comfortable life style while being told what to do.
If you wish retire early and comfortably wealthy, then starting up your own business and working for yourself is definitely the right choice.
However I will say it is good practice to put making a lot of money at the bottom of your list. If you concentrate on making lot's of money it might sidetrack you from actually running a business. Better advice to follow would be to follow your dreams, work hard and then the wealthy lifestyle will follow.

Create something from nothing: One of the biggest satisfactions from working from yourself is building up a successful business out of something that never existed. You will create a massive passion for your business and getting paid while doing this will feel like a bonus.
