Life Lessons?

I was looking for something else and came across this...

CODING / WRITING SOFTWARE

1. Don't over-engineer a solution.
2. There's a whole game of Chinese whispers between what the customer asks for, and what is delivered.
3. Don't forget to check files into source control.
4. Over-estimate how long something will take.
5. Code simply, so the next person can read it.
6. Comment what the code is for, not how it does it.
7. Frequently check with the customer that what you are writing is what they think they want.
8. Learn how to use Google for samples and bug fixes.
9. Whilst writing software, you need to picture the people who will use it.
10. Keep up to date with technology.

WORK IN GENERAL

11. You can only work with what you have, so make the best of it.
12. Being genuinely enthusiastic is good.
13. Find out exactly what criteria you will be assessed against, and make sure you do those well.
14. Training courses aren't all they're cracked up to be.
15. See what mistakes other people make, and learn from them.
16. Each company I have worked for has been better than the previous one.
17. Don't write an email while you are angry. Don't even make any decisions while you are angry. Calm down first. Leave it a day or two.
18. Don't say "yes" to everything.
19. You will make more difference getting better at things you are rubbish at than the things you are quite good at.
20. Keep learning.

PEOPLE

21. At least one of your colleagues will think they are better than you. Hopefully they won't tell your other colleagues.
22. You spend loads of time with your colleagues. Much more than with your family and friends.
23. People keep cropping up when you think you won't see them again.
24. Be helpful.
25. Be careful with first impressions. They are often wrong, so don't trust yours. Other people may judge you on their first impression of you.
26. Don't be smug, arrogant or lead people to believe you know more than you do.
27. Being a gossip is bad.
28. Don't belittle yourself or your colleagues in front of your customer or boss.
29. If you're not very good at one aspect of your job, find someone who is good at it, and ask them to help you.
30. Everyone has good points and bad points. You will be happier if you focus on people's good points.
