The only time you ever truly have is the present.
What if you die? What if you become disabled? What if you lose interest in the dreams you hold now?
What if you dream to trek through the Amazon jungle, and by the time you are ready to, it’s deforested? What if your dream is to stand in Rome’s Colossuem and you never get the chance because it has been destroyed? What if you want to do a home stay with a hillside tribe in Sapa, Vietnam, but they have dispersed and moved to the cities? Environmental destruction happens. Wars happens. Globalization happens. Change happens.
If you hold a dream now, then strive to do it sooner than later; because, as life goes on the opportunity may be lost.
Don’t think if, think when…then make it happen.
