Never decide on anything when you are in the low mood. The low mood will naturally itself distort the facts for you. It is not the right condition to take any big decision.
You have to wait to swing to a good mood when things will be clearer. Always take a big decision only when you are in a cheerful mood, when you are in a positive state of mind. Just like how you decide anything in the light of day when you are awake and not in the dead of the night when you are asleep, in the same way decide this too when you are in awareness and not when in turmoil.
Be very clear, the low also will pass just like the high mood passed. That is the very nature of the mind, it is like a wheel. What is down has to come up. Neither the ‘up’ nor the ‘down’ can be said to be more real than the other. They are both there, thats all.
