The more time spent dealing with problems the less concerning they become when they pop up. Flat tires, wonky computers, whatever, just don’t feel like they did 5, 10, 15 years ago.
Rolling with punches and adjusting helps downplay the deflating feeling of delays. Life experience also helps. Surviving worse or the same can remove a lot of anxiety. You know you can handle it and it’s won’t stop progress.
Every person goes through trials. If you allow them to be lessons rather than losses, they will help you in the long run.
Don’t fret, take on the challenge and know you can do this!
