Are you feeling stuck? Is the project you are working on not going well? Do you seem to be in a rut, and don’t know how to change it?  Maybe you can just think about things differently; maybe you need to physically move and look at the problem from a different angle. Stand on a chair (be safe!), go for a walk and clear your mind, think about something totally different than what is perplexing you. Change your perspective and move on from there.
