One rule I always set for myself is to never lose faith in your dreams and what you try to do.
And if you fail once or twice, keep on trying because eventually you will get it and win! This was the case in my journey in becoming a certified heating and air conditioning specialist.
I went to heating and cooling school and the first time I failed the final exam and was not able to get my certification to become a heating and air conditioning specialist. I could have just given up and went to flip burgers at a local McDonalds or something, but I did not! I invested money a second time to take the course again. And you know what? I passed! The second time was a charm. Today I am an independent heating and air conditioning specialist who has their very own HVAC company with a few workers other than myself. But that is not how it all started. I started as a one man operation in the heating and air conditioning business. It took about 4 years to build up to what I have today. It was a lot of hard work. A few times I wanted to quit and give up, but I kept on trying and did not stop. And it all worked out for the very best. Here I am today being very successful after a rocky start in the business. So my point is, if you fail once, always keep on trying. And if at first you do not succeed, try and try again as the saying goes. It will always pay off!
