Awesome. Great lessons from here @velimir.

The measurement devices don't care or worry, people do

That struck me.
Sometimes people need to learn to look at the obstacles in their life in the same light. They aren't there to trip you up necessarily, but instead they are there to help you achieve something beyond what you thought possible. There is always some more knowledge if you look deeper. I have found out that my only limit is me
if I had to write down what I considered realistic goals for my life 12 months ago I would have NEVER considered that I would be where I am now nor would I have imagined that it was ‘realistic’ let alone possible. I am grateful for how far i have gotten on steemit. At the beginning it was not realistic, but just like you said @velimir,

just as we reach a conclusion to one secret and are ready to act upon our reasoning, several more secrets come to light.

So more passion began to unfold and that is how we should take life. Life has a lot to offer to those who are patient just like @ugetfunded said. I agree with you my friend.
I believe the future holds something way more beautiful than what you might be trying to achieve. So work as much as you can in your present, using the lessons you learnt in past to achieve a future you aspire and let the results unfold! You'd be surprised how beautiful things turn out to be once you become more accepting.
And yes, there is no real life without those grey areas. Life is full of gray areas as we can never predict the result no matter how much effort we put into whatever work we do in our daily life. When we focus only on the present and don’t let our mind wander then the gray areas of life will never bother us. Only when the mind is kept idle will it not accept what is given to one as a reward for effort. Doing goods things and keeping away from all bad qualities will surely help mind stay focussed on the present and stop comparing oneself with others.
Thank you too and enjoy your day too.
