Two things -
Start with thought labeling everytime a thought starts to bubble up label it - like 'planning' , 'past' , 'grudge', 'craving (such as to check email)'
Focus on your nostrils or your belly - choose one and stick to it for several days (wherever you find incoming and outgoing breath sensations are the strongest).
We all go through excessive thinking in the initial phases , but slowly these thoughts will loosen their grip on you - so don't lose heart.
Also if breath meditation is not your thing you should try music meditation - pick a rag based kirtan such as this one and just focus on the shabad with your eyes fully or half closed (try to stay focused on the entire experience including the non vocal beats and muscial notes ), here is an example kirtan
ਗੁਰ ਕੀ ਬਾਣੀ ਨਾਮਿ ਵਜਾਏ ॥
ਨਾਨਕ ਮਹਲੁ ਸਬਦਿ ਘਰੁ ਪਾਏ ॥
On a sidenote stop identifying with being a "ramgarhia" - in fact any label that was meant for our body and we tend to identify with (not just caste, it can be profession, religion, gender, economic status etc) is an obstacle to your deeper understanding of your real self - the fat that you are spirit and not the illusory mix of body and mind -
Man too jot saroop hai Apna mool pehchaan ||
Also for all meditations (music or breathing) do 5- 7 minutes of alom vilom as a warmup .
