Frame

Our mindset can determine our actions.  That's why it's so important.  Stuff happens and that's unavoidable.  We have the ability to respond and not react to stuff.

What is the right response?  It's almost never frustration.  That's a reaction.  A more useful response is probably passion.  Framing the situation is key.  Passion is almost always positive.  I think of a cool word I learned a while back, equanimity. This basically means ability to remain calm.  Being calm seems to almost never be a bad thing.

Frustration is inevitable.  It can be expressed like a toddler, suppressed, expressed as passion, or something more difficult like being calm.  

The positive part is up to us.   That's the mindset piece.  It's important that your actions follow your niyat.  Your actions won't be 100% positive, but cut yourself some slack Taher.  

Taher, be clear what you want your mindset to be. Your niyat can be 100%.
