Do you dream about switching to a career that's drastically different from your current job? It's rare for people to make the leap. The costs of switching may seem too high, and the possibility of success may seem too distant.
The answer isn't to plug away in your current job, unfulfilled and slowly burning out. The answer is to pursue two careers at the same time. Two careers are better than one. And by committing to two careers, you will produce benefits for both.
Subsidize your knowledge development while at your current job, and volunteer your time off-hours to gain experience in a new industry. Your day job can allow you time to learn new skills, and afford you the capital to move on well prepared.
Ultimately, when you follow your curiosity, you'll bring passion to your new careers, which will leave you more fulfilled. And by doing more than one job, you may end up doing all of them better.
