If your career path is going nowhere, resign gracefully and switch careers. Research occupations to find out how much they pay and what their future outlook is (in the U.S., you can find this information in the Bureau of Labor Statistics Occupational Outlook Handbook). Find an occupation that pays well, and invest in the education and/or training to get you that job. Look for employers that offer competitive salaries and ample opportunity for advancement.
Really good article with some great tips. Affiliate marketing has the potential to earn lots of money and I'm hoping I can make it happen. I have tried the matched betting and it DEFINITELY works. The one thing I would say is that you need to check that any bets have been accepted by the bookmaker. I have had on occasion bets which look like they have been accepted but don't register in my account. Always go into your account and check outstanding bets or your bet history.
