for me being aggressive should be focused on when you have a higher paying job and being Wimpy when you have no job to back you up in the journey. I believe someone who has a higher earning with aggressive investment can DCA big fund weekly, and take care of his other responsibilities and have a better emergency fund except the person is a careless or an extravagant spender otherwise there is no point of have a bigger fund and yet lack a better strategic plan. although sometimes peop with high earning are always tempted to spend alot I must confess. you know they say when your money is big your responsibility also increase along with your current financial status. it only takes self decipline to control the urge of excessive or extravagant spending.
