1. "Please do not remain under the misconception that you will win the case before the court."
Sure, a normally educated, upright individual will not be aware of professional unprofessionalism, illegalities, tricks, cheatings etc that lawyers play. Of late, lawyers want to make that fast buck and resort to ANYTHING. It will not be so easy to even contemplate the sort of tricks that the opponent could subject you to. But, be sure that all such tricks or unethical and are illegal acts that attract penal action under law.
But all said and done, lawyers are definitely an integral part of society and their existence is prime. They cannot be isolated, wiped off from society. They are necessary (perhaps evil - if that is what they are) One has to definitely know it distinctly that unlike employees, lawyers do not get paid for coming to office, signing attendance register etc that happens in governMINT rolls. They are a community who depend on contributions, services to eek out their livelihood, carving out their career. Thus, if someone is able to afford a lawyer, is well placed and has a cause to fight a case, hiring a lawyer in the case is a good option and a societal responsibility.
But, you would stand to win if your case deserves it even if you are going to fignt it IN PERSON. You can definitely learn skills to present. Law is clear in this aspect. That Lordship whom you are going to appraise should be fair and not prejudiced for some secretive reason. That is all. If that judge is corrupt, partial etc, then you would surely lose, not if the trial is fair.

2. "you should hard evidence and staying power."
Yes, you should be sure that you have a cause to fight and that the cause is strong enough.
"Staying power" is a tricky ball game. You can be haunted all the where and silenced. There could be personal attacks that you cannot prove, but very frustrating etc. Trust on God. Do your best, do it fairly, keep praying God and keep marching ahead. No force can stop you if you decide to fight your case IN PERSON.
