If you don't save, there's no possibility that you will be able to invest. It's that simple. Everything doesn't look perfect from start and this is the reason why starting off with savings is quite a better way to start.

Also, we have to establish the fact that it's not by who earns the most that is going to have that ability of saving or investing more. Savings and investing involved an high level of discipline regardless the amount of money you're earning. Remember that humans wants are  insatiable and with more money comes the thought that one should fix a lot of wants. If you're not the type that is able to keep all his wants under subjection because of your plan to saving, you might earn the highest amount of money in the room but be the least if them that saves me invest most. Untill you actually starts investing, you will never understand the discipline that's required to be a fruitful investor.
