Do you think good luck play any part of your career?

I think that God is fair and he gave all of us the same luck. Some catch it, some don't.
I dont think that you can prepare for luck or an opportunity because by definition, you never know what form will be luck and when it will knock on your door.
Here are the attributes of those who catch, I see 2 main ones:
1- they are open minded in ideas, open agenda - means they give themselves time for new people encounter.
2- they have a plan, they know what they are aiming at in a 5-year plan.

Say God gives You and Mr. U (Unlucky) 5 day chances out of 365 days x5 years. 1825 long days. I am going to explain how Luck knocks on your doopr but not on Mr. U door
You know you want to start your HR company, your colleague Mr U also dream like you.
You plan that in 5-years so you plan roughly YR1= learn HR accounting, YR2= learn management, YR3= get experience selling HR service, YR4= find capital, YR5= recruit and start.
Day 1: Tomorrow, you meet Thanh and Winnie Lam at a HR cocktail inviting Scancom explain their services. You seize the opps to ask what you need about starting a company and capital (Yr3+Yr5 done!). Mr. U at the same cocktail don't even know who they are.
Day 363: there is a seminar on private equity investment fund, you go and collect card and ask if they invest in HR start-ups (YR4 done). Mr U why should I go now, I will think about capital when I am trained.
Day 500: Your colleague at accounting payroll is absent for 1 week, your boss asks you to work over time and do the work (YR1 done). Mr. U feels he is very unlucky to have been chosen to do double work for 1 week!
Day 1001: there is a New RMIT program for the summer holidays: mini-MBA in 4 weeks for just 1,500$ launching price. No money? you sell your Honda SH 5000$ for a brand new PCX 3500$. Finished Yr3 in 1031 days instead of 1825 days (5 years right?). Mr U. no question I sell my SH and don't go on holidays!

Then you think, I have done all YR1-2-3-4-5 already, what if I spend that money from investor, it's my 1st time, what if I cannot recruit, I cannot sell. My friends say I am crazy to quit my hard earned manager's job
If my wife lose her job and I have to keep my good and regular salary at Scancom...
Your luckiest day is on
Day 1099: You employer fire you! You are now free to start your company! Mr U. is really unlucky because Luck never knock on his door!
