Lawyers in litigation / Dispute Resolution in HC / SC / NLCT / NCLATs and other forums how do you manage frustration as after mentioning of a matter , the matter may take few years to reach stage of final hearing . It makes me feel like a fool that a simple appeal has to sit for 2-3 years and then the stage of final hearing will come . How bad is it ?

Just rub one off

Why are you worried? Bill the client and chill.
