Rejection and failure is a constant companion in man’s life. Don’t be afraid of either and face them directly, learn to get used to it without letting them brake you. Success often comes from learning from many tiny failures. It’s pointless to say “don’t be afraid,” it’s better to face them as bravery. Bravery is doing what you’re afraid of and ignoring the fear. Each time you face something new, it will literally change you as it will rewire your neural pathways and make you more resilient.
Wearing a suit is awesome. It can make you feel like a million bucks or like you have superpowers. Try it, and it might feel strange the first time you do it, as you’re not used to it. And you will, you will get used to it. When you do it, make sure it fits you in the shoulders and chest, the sleeves and trousers will almost always be too long, but both of those can be hemmed or tailored to fit you for relatively cheap; or learn to sew yourself, at least hemming trousers is quite easy and quick.
If you are contemplating outsourcing some of what you could do but don’t have time for, and know someone who can do 80% of that thing as well as you can without much instruction, delegate it immediately and don’t fuss about the tiny details. Perfectionism will kill the product before it even launches if you obsess over it too much.
Respect can easily be lost, and a bad reputation spreads 7x faster than a good one, so do everything well, be respectable and respect the others, serve the Lord and by proxy the people as if you served Him. But don’t let people abuse you and your talents. Don’t let them walk over you.
Never lie. It will come back to haunt you. Instead, always tell the truth. Telling the truth doesn’t mean you have to say everything. Choose your words carefully, don’t feel the urge to reveal everything. Just don’t lie.
Be wise with your words. Don’t speak too much. It’s better to listen more and speak less, but what you do say should be thought through. Everyone can have opinions, but not every opinion always has to be shared. Also, don’t fall in love with the idea of something or someone too much. It may consume you and it very well might be sinful unbeknownst to you as you do it.
You can only ever be responsible for your own actions and own response. Don’t try to carry the weight of owning response and actions of someone else. Especially if you don’t like them. Besides, you were not made to carry the weight of the world, Jesus already did that!
Everyone thinks much more about themselves than about you. So don’t be afraid to try to do something in front of people, like public speaking for example. It’s not a question of will you make mistakes, but when and how many, and yet most people don’t care as much about those and won’t ever remember them, but you might. Don’t stress about how it turned out, and stop caring about other people’s opinions. The more you ask the more the mistakes only you noticed will become evident. Keep them to yourself. Instead be thankful for opportunities when they present themselves to try even if you fail. And fail you inevitably will. But that’s okay. One can’t rise if one hasn’t fallen.
Finally, always be grateful and thankful to God for everything, the evidently good, and for what you perceive as bad, because only God can use what you perceive to be bad for good in the long run if you trust Him on that. Trust Him, for through Jesus you can be a new creation, and you are.
