The most important things are the relationships you have with the people you love, and the environment you expose yourself to. Always remember that people you spend your time with and places you are in, are much more important that what you do. If you do not like something or someone just say no.
That’s why I’d like to share with you my “20’s rule”. Yes, that’s the magic rule that save you in many different ways.

Every important decision must be made in 20 seconds
Don't let your convoluted, preconceived and belief-based reasoning get the upper hand. Decide by instinct, you will have the least chance of making mistakes.

Always be ready to change your plan in 20 minute.
That’s give you an huge advantage, people are generally indecisive and take a long time to make a decision or change a plan. Be fast, 20 minutes.

Exercise 20 minutes
Do 20 pushups ( for 3-4 series), 20 squats, 20 pull-ups (5x4).. Run 20 minutes, do 20 minutes HIIT..

More examples: when I find the right camping spot, I set up tent, sleeping bag, I check the bike etc in no more that 20 minutes. In the morning I can leave my warm sleeping bag, pack up my stuff and be on my bike in 20 minutes. Some travellers need hours, I prefer to save precious time to enjoy the nature around, read my book, do some exercises or sip a cold beer.
Same with hotel room, hostel etc. From the bed to the bike, 20 minutes.
If you do not like someone, politely leave her/him in 20 seconds. Cut the conversations, just do it. Own 20 things, be focused on the 20% of things that really matter, repeat something 20 times and you’ll master it, eat 20 grams of protein at every meals.. I can go on hours. Oh man, never forget the magic of the 80/20 Pareto rule! My favourite ever.

Catting time to your thinking system improve your instinct to take a quick decision and, trust your guts, they never lie.

Always be ready to change plan in 20 something.. That’s what I do, and it works.

How long did it take me to write this post? Yeah, you already know the answer.
