I read somewhere that the most important things in life happen to us when we are busy making other plans, when we least expect it.
This proved to be true reflecting on my personal past.

We tend to "get used" to what we have and feel a special comfort in it, even when we are suffering, even when it makes us suffocate and makes our present a living hell. 
We have several kinds of fear:
fear of change,
fear of the idea of having to work something anew,
fear to be disappointed again,
fear of going through the same shit again,
fear of failure,
fear of not being up to expectations,
fear of having really found what we always wanted,
fear of being happy,
fear of actually changing a life full of discernible patterns on any level whether psychological, emotional, relational, professional, etc...

Taking the plunge into any new adventure/project, no matter its nature, requires lots of guts and it becomes harder to achieve the older we get. One being a thinker and sensitive by nature makes things even harder.

I have learned that the best moment of any life-changing decision is the moment you take the aforementioned plunge, because you are never fully ready to any change in your life.

So, next time you know what you have, do not think of what may be, just take that plunge and see where it will take you.
The unknown is beautiful if your present base is solid and beautiful.

So, my friend, are you ready?
