Frustration is the theme really.
You can overcome obstacles by chanting everyday. Buy a 108 beads mala and man up and start chanting every day. Life will be 100 times easier.
You are not the only one going through a Sade Sati, every one goes through it when its time its time. Put your seat belt on. Learn to be patient, thats the key. Saturn doesnt like haste. Things will move slow causing frustration, thats how it is. If you work hard and chant every day Saturn will reward you like anything but it takes time.
