What is the most difficult part of being a founder?

To remind oneself that the lows can get deeper and the highs can get shallower.

Oh man where do you start? Managing multiple responsibilities, dealing with setbacks and failures, "being your own boss" sometimes isn't as fun as people may think, it comes with long working hours and sacrifices.

For me, it is various psychological aspects behind dealing with the constant flow of unknowns.

Being unsure about every decision at first.

As a founder, the most challenging aspect is navigating the constant uncertainty and ambiguity that comes with building something from scratch. It requires wearing multiple hats, making tough decisions, and persevering through setbacks. However, the opportunity to create and make a positive impact makes it all worthwhile.

Reading all the comments and I think willing your startup to success captures the challenges everyone has mentioned below. It's hard and tiring, but it should be. Creating something great requires strain and difficulty. In many regards, every day you have to create the success you want your startup to achieve Embrace the challenge and get comfortable with the hard and uncomfortable! My advice to get through this is to reflect on how much you have achieved to this point to drive your entry into a new phase, task, or responsibility! As a first-time founder launching the first half of our marketplace come July 17th, everything is new and uncomfortable in some respects but I'm excited about what we've accomplished and even more so about what we can achieve.

That is very insightful @divine_rivers1 Looking how far one has come since the start, does help on the bad days.
