We experience a phase where everything just clicks; not just for one random day but for weeks! Most won't remember the details of when and how it started; it feels like you swallowed liquid luck and the universe shifted to work for you.
This magical phase is cyclic. The key is to recognize and capitalize it, and increase the surface area of luck.
To recognize it, watch out for some signals: A lot of opportunities appear, you feel in control, obstacles are dissolved quickly, you have a better momentum... etc.
To capitalize on the moment, make bold moves. "Have almost too much self-belief", as Sama says. Make that career switch, take on that ambitious project, pitch your ideas, be more vocal in meetings, work outside your comfort zone, build new skills, work harder, go on that date... You know where you're holding yourself back; push past those barriers.
If you plant the right seeds, they will continue to grow beyond this phase. You will increase the surface area of luck, and returns will compound.
The point here is not to wait and watch for the phase to come and do all the above. It is to sail faster with ease when the wind is on your side. Make the journey more rewarding.
