What did you learn recently that could be useful for entrepreneurs?

Entrepreneurship is about solving problems.

It's not about building a big company - It's about solving big problems. The bigger the problems, the bigger the company.

Work backwards from your goals. Break down your goals to smaller milestones and start there.

It's important to take a step back, plan, and then execute. Blind execution without clear planning leads to nowhere. Planning without execution leads to nowhere too. Balance is important.

Be less interested in being right, and be more interested in the truth. It's better to be "rich and wrong" than "right and poor".

Making decisions based on data is far more effective than making decisions based on gut feeling / opinions. Communication is also far more effective with data too.

Focus on what you're good at, and delegate what you suck at.

If you don't have clarity on how you're going to make it, you'll never know how you're going to make it.

Attitude is far more important than Aptitude. One can be trained, the other is set for life.

Raising funds is all about raising more funds. 

It's not "what you need to do" in order to become successful, but rather "who you need to become".

If you never did it, it's harder to show others how to do it.

Entrepreneurship is 1 day of glamour, and 999 days of blood, sweat, and tears.

One of the interesting thoughts I had experienced is the power of disagreement and I think this applies especially to companies with authoritative hierarchies.

This is because with disagreement, we would foster and encourage discussion amongst different perspectives. One of the examples we can see from the past is that Socrates says that the best way to find truth is with the exchange of opinions and discussion where he would even host discussions in the Town Square of Athens to encourage debates. 

Another example would also be how the free market in the US could inspire many innovations.
