Ever wonder which jobs to do to make it to your next level?
Use this spreadsheet, just fill in your currnent energy, experience points, and points needed at the top.
Then fill in the experience gained and experienced used columns for the jobs you are looking to to.
Choose jobs with an equal or higher percentage than the "do jobs with this %" value.
This will allow you to level up before running out of energy.
Also, sometimes you will get bonus experience points when doing a job. when this happens, adjust your spreadsheet as the percentage needed will decrease slightly when this occurs.

Example

				do jobs
have	next lvl	need	energy	with this %
351061	354025	2964	1561	1.898783
		exp gained	exp used
steal bank records		38	27	1.407407
dodge fbi tail		29	18	1.611111
invade tong neighborhood		32	22	1.454545
order hit		59	31	1.903226
embezzle		75	45	1.666667
settle a beef		69	36	1.916667
obtain compromising photos		34	25	1.36
		75	45	1.666667

in this example, you would do the order hit or settle a beef jobs until you level up.
when you get down to about 100 energy, your percentage should be at 1 or less than one.
at that point, you can go back and do jobs that you actually need to complete and still make your level up.
