Not admitting times are good, means getting rid of the responsibility. When you say the odds are stacked against you, all it does is get in your way.
Odds go in your favour and then they don't. Life is a never-ending stream of problem-solving.
Some will be harder than others. Some will be easier. Some may have been solved before, some may require something novel.
But when you admit you've got an opportunity. An opportunity to make the thing you want to make. To work on the things you want to work on. To take care of the people you want to take care of. You give yourself a responsibility.
Now it's up to you.
