Some changes are for the better.
Some changes are meant to realize what we had and maybe be more grateful if you get to have it back. In other words, mature a little.
I recently switched jobs. I am a consultant working at a top 4 now! I am busy but I am happy.
I am single now too.
I am always tired yet so grateful to learn something new everyday and for being considered to carry out higher responsibilities.
Life is an on-going path and just switched to a greener one.
