Finding the stamina / inspiration to tackle problems and resolve things that seem insurmountable

Deal with this a lot - mostly my own doing (problems with my old vehicles, or issues around parenting my daughter, or fears about dating/relationships, or issues with work) but I find I often run out of drive/stamina to get stuck into things and tend to delay and put off solving issues because things seem overwhelming.

My way out is to back right off and force myself to take time out and re-focus. often this leads to more delays but eventually solutions are achieved, however new issues are never far away.
