Have you established a Plan B source of income? Have you thought about what you would do if you lost your job in today's volatile and uncertain economy? Personally, I believe everyone should have at least one part time, self-owned business. Just the tax benefits alone are worth having your own part time business. Schedule C, from the IRS, allows you to write off a lot of various expenses from a sole proprietor business that you would never be able to claim if your only source of income is from a W-2 job as an employee. Almost everything can be applied to your businesses; write off meals, travel expenses, phone, internet, utilities, stationary, uniforms, business wear, and work clothes. This significantly reduces the taxes that you owe each year. Are you able to claim all of those things with your current W-2 job?
Do you have a hobby that you can turn into a business? Have your ever had an idea you feel could make honest money? Don't put it off. Start now. You don't need to dump a lot of time or money into your idea to start. Start small and slow but be persistent and don't give up.
Find something you like and pursue it. Even though you may not have the experience, or there may not be much money to be earned, in what you like and want to do, the better you become, the more money you can earn. There are many business ideas and opportunities that can be found on the internet. Be careful, however, because there are also a lot of scams. Do lots of research before investing your hard-earned money.
Don't delay. Start now. Even if you don't lose a job, you can earn extra income on something you like to do and, if you do lose your job, you will have established a business that may be able to sustain you.
