Try to have at least 3 separate accounts:
(1) Day to day account
(2) Savings account
(3) Investment account
The Day to Day account serves as your daily expense account. You should take time to set the daily, weekly and monthly expenses that you are incurring so that you could move the excesses to your two other accounts.
The Savings account is your piggy bank. This should not be less than 6x your monthly expense. The reason for this is so that you could survive for 6 months if you lose your current source of income (day job).
The Investment account would be your money pot which you could gamble away on several investments (stocks, mutual funds) or to store your funds for something like your own business. You should only deposit to this account when you have reached the minimum amount in your Savings account.
