Programming Achievements: How to Level Up as a Developer

1. Select a particular experience to pursue.
2. Pursue that experience to completion. (Achievement unlocked!)
3. Reflect on that experience. Really soak it in. To get the most out of each achievement, you owe it to yourself to pause and reflect on the experience before you move on to the next one. Introspect. Ask yourself what you learned. Take the time to write down those thoughts. And even better still, share them with someone else and see how your learnings compare to other people who've also earned this achievement.
4. Return to Step 1, this time selecting a new experience.

Mahatma Gandhi

Live as if you were to die tomorrow. Learn as if you were to live forever'~

Randy Pausch

Brick walls are there for a reason. They show you how much you want to climb over the wall and achieve that goal.

Steve Jobs about creativity

Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn’t really do it, they just saw something.

## searching with regular expressions
you can use regular expressions while searching for something ex:
    db.airports.find(name: {$regex: "[^\s]paris", $options: "i"})
this regex matches every document in airports collections whichs name start with paris
or include whitespace character and then paris. but this will't work as expected because
in strings \ character works as escape character so we need to excape it too
this will work as expected:
    db.airports.find(name: {$regex: "[^\\s]paris", $options: "i"})

about writing
---------------
Write 50 words. That's a paragraph.
Write 400 words. That's a page.
Write 300 pages. That's a manuscript.
Write every day. That's a habit.
Edit and rewrite. That's how you get better.
Spread your writing for people to comment. That's called feedback.
Dont worry about rejection or publication. That's a writer.
When not writing, read. Read from writers better than you. Read and Perceive.
