Startups are about hardwork, giving it your all, and believing in the vision
It may be cliche, but all startups start with great leadership. Whether it's one person, or a group, leadership is key.
Without teamwork, NO startup can succeed. Leave no one behind!
Be Open minded
There's no such thing as a stupid question. Be open in accepting criticism, feedback, and ideas from others.
Don't over stress, sometimes it's great to take a break, collect your thoughts, and relax.
If you're not having fun, maybe it's time to move on. Push forward only if you truly believe in the vision, and enjoy pursuing it.
