Being in the zone

Anyone who watches sports knows what being “in the zone” looks like. If you are actively playing sports, you probably also know what it feels like: basketball players almost never miss a shot, even seemingly impossible ones. Soccer goalies suddenly look bigger and seem to make their goal impenetrable. Baseball players get on crazy streaks of hits, home runs or pitchers striking out anyone that comes against them. It’s like you just drank some magic fluid that made you superhuman.

Local maximum

Being at a local maximum is a little like being on top of a mountain; every step in any direction is a step down – you are at the highest point in the area. But there’s a higher mountain, with a much higher summit. To reach it, you must first go down, and then go up again – in fact, you have to work much harder than you did to climb your current mountain. Should you leave your local maximum in search of a better result? Or should you stay on the top of your current, high-but-not-highest mountain top?

With January 1st approaching, it’s tempting to decide on a big new year’s resolution. If you are a startup founder, maybe you’ll use this turn of the calendar to make a big step or commit to a change in direction. But before you do, hear me out.

Everybody knows the role of a leader is to lead the team, and everybody knows the startup’s founder is the team’s leader. But not many understand what the real role of a startup leader is, and how much it’s different than the role of a typical team leader in a regular company.

Where are you based?

For me, skydiving - jumping out of an airplane with a parachute - sounds like a terrifying experience. I will probably never do it in my entire life – much too scary for me.

But some people jump out of planes for a living; for them, skydiving is not a big deal. Even for those who did it two or three times feel like although it’s still a bit scary, it’s no longer a big deal.
