There are 2 types of saver:
Saver A will put any spare savings (if any) away at the end of the month and Saver B, who will pay themselves first at the beginning of the month.
Saver A rarely increases their wealth significantly as, whatever their monthly income may be, there is little left at the end of the month.
Saver B will, over a period of time, accrue far larger funds and will therefore have a much higher chance of achieving financial independence.
Which type are you?
So commit NOW to setting up a monthly savings plan (ideally an equity based ISA) if you want to have sufficient capital and/or income for your unknown future life.
If you are already doing so, consider increasing the monthly amount you put away. You will not regret it.
