Work smarter, not harder!
Use Paretos 20-80 principle.
Paretos principle: It says,
20% of your work results in 80% of your result
80% of your work results in 20% of your result.
Go for that 20% and eliminate the uneffective 80%.
Discussion
People always forget that this principle goes even further:
20% of 20% = 4%
80% of 80% = 64%
-> 4% of your work results in 64% of your result
20% of 4% = ~1 %
80% of 64% = 51%
-> 1% of your work results in 51% of your result
