Self trust.

I remember when I first started teaching how anxious I was until I realised that I was not alone. If I had a situation that I found challenging, I could always consult older and wiser heads. It gave me great peace of mind to know that I had 'back-up'. As my own experience grew I found I was able to offer similar comfort to teachers new to the profession and especially to those I was training to become teachers.
I apply a similar thought pattern when I approach difficulties in everyday life. Firstly I ask myself is there anyone I can trust to help me with the problem. Secondly I ask myself if I already trust myself enough to handle things on my own. More often than not the answer is a resounding 'yes'.
Try this approach yourself, you may find it useful.
