People can always come up with an excuse as to why they cannot do something. Excuses sound best to the people who are making them. Do not wait for the conditions to be perfect because they will never be perfect. There will always be doubters and people that do not believe. Build a support system and put yourself in an environment where you will thrive. Surround yourself with people who have energy and look at the day as an opportunity. Start believing yourself and stop believing the doubters.
