If you can create an environment where genuine praise is given freely, the people within that environment will be much more able to develop themselves and live to their potential. 

Too much criticism saps the desire to move forward. 

There are several views on what 'too much' actually means, but research has shown that healthy, lasting relationships are likely to have a ratio of 5:1 positive:negative interaction. That means 5 positive comments to one negative comment, can you think of an example of a relationship where you manage to do this?   

There are many things we have no control over, like the weather and world events, and if they are bad we accept it.   There is no question of taking personal responsibility or blaming ourselves for things we have no control over.   However when it comes to people and relationships we often blame ourselves or feel bad because of other people’s behaviour.   Try to adopt the same attitude to someone’s bad behaviour as you would to the weather or anything else you have no control over.   Remember the only thing we really have any control over is our own reactions to events.
